The grip is super comfortable and I'm a big fan of how its angled. Despite being left handed, the stock (when folded) still has a good feel.

My only gripe really is how the selector rubs on my hand when gripping the KMP9 while on semi-auto. Its easily fixed by rounding off the edges of the selector that comes into contact with my hand. Also, wearing gloves prevents the selector from digging into my hand when I have my natural grip on it.
